Actually kinda on point for a true enthusiast of something to call an important place the "promised land". She's definitely off to try new clothes with him in tow. Her putting on that scarf is kinda like an otaku putting on a headband... Then again, she's already pretty much a frilly clothes otaku, isn't she?
I can already imagine him carrying a big bunch of shopping bags after this. Of course we also get to see her trying on the new clothes, right?
